Insects, 1 735 



This species varies in respect to the colouring of the wings, which 

 are sometimes only slightly coloured, although generally dark, as de- 

 scribed : it is a local species, but I have taken it plentifully in June, 

 near Darenth Wood, Kent. T have not met with it in any other 

 county. I found it burrowing in a perpendicular sand-bank : they 

 are very partial to thistle-heads, from which they collect pollen.

 white pubescence ; the pubescence on the thorax is white, with a 

 broad black band between the wings, which are hyaline, having 

 a dark cloud at their margins ; the anterior femora have a fringe of 

 long white hair beneath ; the tarsi are fuscous beneath ; the claws

 blue-black, smooth and shining ; the anal fimbria nigrescent. 



Male. — (Length 5 — 6 lines). Black; the face clothed with white 

 pubescence ; the antennae nearly as long as the head and thorax, the

This pretty bee appears in May ; it is very abundant about London, 

 particularly in Hyde Park, where it constructs its burrows in the 

 hard trodden pathways.
